Support for household appliance, and household appliance

ABSTRACT

A control method for opening a door of a drum washing machine comprises the steps: S1, receiving a door opening instruction sent by a user; S2, judging whether a water level at a front end of a drum assembly satisfies a condition of opening the door, if yes, entering step S4, if no, entering step S3; S3, tilting the drum assembly with a tilting mechanism, and then returning to step S2; and S4, unlocking a door lock. Through a manner of lifting a front end of the drum assembly, the operation of opening the door during running is realized. In this way, the original parts of the washing machine do not need to be changed, and the drum assembly is tilted only through a driving device arranged at a lower part of the drum assembly or through a hanging spring arranged at a top part of the drum assembly.

TECHNICAL FIELD

The present disclosure relates to a technical field of support levelingof household appliances, and specifically relates to a support forhousehold appliance, and a household appliance.

BACKGROUND

Generally, leveling devices are arranged at bottoms of shells of thehousehold appliances, the household appliances can achieve a stableplaced state through regulating the leveling devices when the householdappliances are placed, and the leveling devices can support thehousehold appliances and keep the household appliances stable after thehousehold appliances are placed in a leveled manner.

Taking a washing machine for example, bolt supports are generallymounted at the bottom of a shell or whole set of the existing washingmachine, each bolt support comprises a lead screw, a nut gasket and arubber pad. The nut gaskets can be screwed up and down on the leadscrews, the lead screws can also be screwed up and down in screw holesof a bottom plate of the shell, and the height regulating of the washingmachine is achieved through lengths of the lead screws of the boltsupports screwed in the screw holes of the bottom plate; for a majorityof washing machines, heights are increased through counterclockwiserotation of the supports, the heights are reduced through clockwiserotation of the supports; and after the heights of the bolt supports areregulated, the nut gaskets for preventing loosening are screwed down tokeep steadiness.

For the supports of the washing machine, although the leveling of thewashing machine is achieved, users are required to carry out manualregulation, and user operation is extremely inconvenient if the deadweight of the washing machine is relatively heavy or a setting space isnarrow and small. In addition, during the long-term working of thewashing machine, vibration also acts on the leveling supports, thesupporting failure of the leveling supports is easily caused, and thus,the out-of-flat placement of the washing machine is caused.

For example, the existing 8 KG drum washing machine is generally about80 Kg and is relatively heavy, the regulation by customers is extremelyinconvenient, the condition that the washing machine is regulated to anoptimum state cannot be guaranteed even if the regulation is completed.During the washing, particularly spin-drying dewatering of accelerationto 1400 r/min from 0 r/min of the washing machine, great vibration willbe caused once the washing machine is not horizontal or suffers from afailure support problem, and thus, the comfort of use of the customersis greatly affected.

In addition, the vibration caused by the out-of-flat of the washingmachine may loosen screws of the supports, supporting brackets of thesupports may vertically move, a horizontal state of the washing machinemay be changed by the instability, and vibration that is more intensiveis caused. Due to the vicious cycle, the noise of the washing machinewill become louder and louder in long-time use, certain damage to thewashing machine is caused, and the service life of the washing machineis shortened.

Therefore, the leveling of the existing washing machines has theproblems of manual regulation, time and labor consuming and relativelypoor accuracy.

Taking this into consideration, the present disclosure is provided.

According to the support for household appliance, provided by thisembodiment, based on the hydraulic principle, the support can performadaptive regulation automatically by means of the fluidity of thehydraulic medium for different pressures resulting from unflatness, thehydraulic medium stops circulating until the support for householdappliance achieves balance, and thus, automatic leveling is achieved.

The support for household appliance of the present disclosure comprisesa fixing member and a protecting member 1300, the fixing member or theprotecting member 1300 is embedded in the protecting member 1300 or thefixing member which brings the following technical effects.

1. The fixing member and the protecting member 1300 of the presentembodiment are embedded and installed, which can play a limit function,avoid setting a complicated limit structure, and is simple and stable.

2. The protecting member 1300 and the flexible accommodation body 600 ofthe present embodiment are closely in contact with each other with nogaps in between. The expansion rupture of the accommodation body 600 isavoided when the support for the household appliance is under greatimpact pressure (e.g. when the household appliance or any object withthe support for the household appliance installed is dropped or liftedor suddenly placed), the reliability is improved.

3. The fixing member and the protecting member 1300 are embedded andinstalled, so the installation heights of the fixing member and theprotecting member 1300 are decreased, further the whole height of thesupport for household appliance is decreased. When the support forhousehold appliance is mounted on the household appliance, it has lessinfluence on the overall center of gravity, which is more conductive tothe support stability of the household appliance, and has better shockabsorption effect on the vibration during the working process of thehousehold appliance (such as the dehydration vibration of the washingmachine).

The implantation of the present embodiment is that the fixing member isembedded into the protecting member 1300, and it also can be that theprotecting member 1300 is embedded into the fixing member. In addition,the embedding of the present embodiment can be partial embedding or allembedding

As a preferred embodiment of the present embodiment, one end of theprotecting member 1300 is provided with a protecting curved surface1305, and the protecting curved surface 1305 is matched with the outersurface of the flexible accommodation body 600 to prevent the flexibleaccommodation body 600 from being damaged by pressure. The protectingmember 1300 of the embodiment is provided with a protecting curvedsurface 1305, such that the flexible accommodation body 600 can beattached to the protective curved surface under pressure to protect theflexible accommodation body.

The other end of the protecting member 1300 of the present embodiment isprovided with an insertion groove 1302, and the fixing member isembedded in the insertion groove 1302 of the protecting member 1300. Thefixing member of this embodiment can be partially embedded in theinsertion groove 1302 or can be entirely embedded in the insertiongroove 1302.

The protecting member 1300 of the present embodiment moves up and downduring the expansion and contraction of the flexible accommodation body,and needs to limit the circumferential rotation of the protecting memberduring the movement of the protecting member, so that the flexibleaccommodation body can be better protected and to ensure the stabilityof the support for household appliance during leveling. Therefore, thefixing member and/or the protecting member 1300 are/is provided with alimiting mechanism for limiting the circumferential rotation of theprotecting member relative to the fixing member.

As a preferred embodiment of the present embodiment, a limitingprotrusion 1304 is provided on the inner wall of the insertion groove1302 of the protecting member 1300, and a limiting recess 506cooperating with the limiting protrusion 1304 is provided on the fixingmember. The limiting structure of the embodiment is designed accordingto the embedded installation of the fixing member and the protectingmember 1300, and the limiting movement is realized at the same time ofthe embedded installation, and the structure is simple, stable andreliable.

Specifically, the flexible accommodation body 600 of the presentembodiment comprises an opening part 601 and a retractable accommodatingbody 602; the opening part 601 is sealingly mounted on the hydraulicplate 100 by the fixing member; the protecting member 1300 is arrangedbetween the accommodating body 602 and the fixing member; the fixingmember is embedded into the protecting member 1300; and the protectingmember 1300 is provided with a protecting curved surface 1305cooperating with the accommodating body 602. Since the leveling of theregulating support 300 is mainly depending on the axial movement of theflexible accommodating body 600 which is driven by the extending andretracting of the accommodating body 602 under pressure, thus, theprotecting member 1300 is disposed between the accommodating body 602and the fixing member. The flexible accommodation body 600 is protectedby the protecting curved surface 1305 to avoid damage, ensuring stableand effective leveling and prolonging the service life.

Further, the fixing member is a pressing ring 500, and the pressing ring500 includes an annular body 508. The inside of the annular body 508 hasa pressing ring opening 507. The opening part 601 of the flexibleaccommodation body 600 passes through the pressing ring opening 507 andis sealingly mounted to the hydraulic plate 100 by the annular body 508.The protecting member 1300 comprises a protecting ring 1301, and aprotecting ring opening 1303 for allowing the opening part 601 to passthrough is provided inside the protecting ring 1301. The insertiongroove 1302 for allowing the pressing ring 500 to be inserted isprovided in one end, closing to the pressing ring 500, of the protectingring 1301. The protecting curved surface 1305 is provided on one end, intouch with the flexible accommodation body 600, of the protecting ring1301.

The pressing ring 500 of the present embodiment is fixed to thehydraulic plate 100, and presses the opening part 601 of the flexibleaccommodation body 600 between the compression 500 and the hydraulicplate for sealingly mounting. A liquid passage is formed inside thehydraulic plate 100, and the flexible accommodation body 600communicates with the liquid passage after it being sealingly mounted tothe hydraulic plate 100.

A depth of the insertion groove 1302 of the present embodiment is largerthan a thickness of the pressing ring 500 so that the pressing ring 500can be completely embedded into the insertion groove, thus, the mountingheight can be minimized to reduce the overall height of the support forhousehold appliance. At the same time, when the supports for thehousehold appliance are in an uneven state, the flexible accommodationbodies 600 are subjected to different pressures, and the liquid mediumflows, and the flexible accommodation body 600 telescopically drives theregulating support 300 to axially move in the sheath 200 for leveling.The expanding and extracting of the flexible accommodation body 600 willact a force on the protecting ring 1301, the protecting ring 1301axially moves under the limiting of the insertion groove 1302 and thecompressing ring 500.

In the present embodiment, the outer circumference of the protectingring 1301 is designed to completely wrap the pressing ring 500, and onlythe protecting ring 1301 can be pressed into the regulating support 300,which greatly improves the reliability and the stability of the fit.Therefore, after the protecting ring 1301 is pressed into the regulatingsupport 300, it will be stably moved in the axial direction of theregulating support 300, and the movement is smooth and reliable. Thecooperation of the two makes the whole support for household appliancemore stable and a certain amount of activity up and down is provided forboth the protecting ring 1301 and the pressing ring 500.

To further limit the circumferential rotation of the protecting ring1301, an internal wall of the insertion groove 1302 of the protectingring 1301 of the present embodiment is provided with at least onelimiting protrusion 1304, an outer peripheral wall of the pressing ring500 is provided with the limiting recess 506 corresponding to thelimiting protrusion 1304.

The limiting protrusion 1304 of the present embodiment is formed by theinner wall of the insertion groove 1302 partially protruding inward, andthe limiting recess 506 is formed by the outer peripheral wall of thepressing ring 500 partially recessing or being removed.

Preferably, a plurality of limiting protrusions 1304 are provided, whichare respectively distributed along the circumferential direction of theinner wall of the insertion groove 1302. A plurality of limitingrecesses 506 are provided, which are correspondingly distributed on theouter peripheral wall of the pressing ring 500. In this way, thestability of the circumferential rotation limit can be increased.

Further, the limiting protrusion 1304 has an arc-shaped limiting outerconvex surface, and the limiting recess 506 has an arc-shaped limitinginner concave surface, and the limiting outer convex surface and thelimiting inner concave surface cooperate with each other. In this way, asmooth transition between the limit structures can be achieved, which ismore conducive to the stable adjustment of the support for the householdappliance.

Specifically, the flexible accommodation body 600 of the presentembodiment comprises a small-diameter part 603 communicating with theaccommodating body 602, an inner diameter of the small-diameter part issmaller than an inner diameter of the accommodating body 602. The endpart of the small-diameter part 603 is flanged to form the opening part601, the fixing member sleeves on the small-diameter part 603 tosealingly mount the opening part to the hydraulic plate 100. Theprotecting member 1300 sleeves on the small-diameter part 603 and islocated between the accommodating body 602 and the fixing member.

An outer diameter of the protecting member of the present embodiment issmaller than the inner diameter of the regulating support 300, thus,when the regulating support 300 moves axially in the sheath 200, theprotecting member 1300 moves into the regulating support 300, and itdoesn't affect the regulating height of the regulating support.

According to the embodiment, the hydraulic medium in the flexibleaccommodation body 600 flows through the liquid flow passage 107 in thehydraulic plate 100, and the accommodation chamber is formed by thehydraulic plate 100, the sheath 200 and the regulating support 300.Therefore, in order to guarantee that the hydraulic medium in theflexible accommodation body 600 can enter the hydraulic plate 100, ahydraulic plate groove 104 is formed in an end face of a part, embeddedinside the sheath, of the hydraulic plate 100; the flexibleaccommodation body 600 has an opening part, and the opening part of theflexible accommodation body 600 is deformed under pressure of a pressingring 500 and fills the hydraulic plate groove 104 for sealing. Accordingto the embodiment, the hydraulic plate 100 is partially embedded in thesheath 200, so that the hydraulic medium in the flexible accommodationbody 600 can circulate into the liquid flow passage 107 in the hydraulicplate 100 by directly mounting the flexible accommodation body 600 tothe embedding part in a sealed manner.

Preferably, the hydraulic plate groove 104 is formed in the end face ofthe embedding part 108.

Embodiment VII

The embodiment also provides a household appliance with the support forhousehold appliance, provided by any one of the above-mentionedembodiments. The household appliance comprises a casing, wherein aplurality of household-appliance-used supports are mounted at the bottomof the casing, and a hydraulic medium being provided in thehousehold-appliance-used supports 1000 circulates among thehousehold-appliance-used supports for leveling.

According to the embodiment of the present disclosure, taking a washingmachine for example, a principle and a method for automatic leveling ofthe washing machine by using the support for household appliance,provided by the present disclosure, are elaborated. After the washingmachine is mounted, different household-appliance-used supports aredifferent in horizontal height due to an out-of-flat ground surface, andthe household-appliance-used supports located at pits of the groundsurface are low in position. Thus, the household-appliance-used supportsat high positions firstly bear the weight of the washing machine andbear a large gravity force, and the household-appliance-used supports atlow positions bear a small gravity force due to failure support.

Regulating supports of the household-appliance-used supports at highpositions move up under high pressure, heights of the entire supportsare reduced, thus, volumes of hollow chambers of flexible accommodationbodies full of the hydraulic medium are compressed and reduced, thehydraulic medium is forced to enter throttling holes or valve holes andenter the household-appliance-used supports at low positions throughhigh-pressure pipes, thus, the hydraulic medium in flexibleaccommodation bodies of the household-appliance-used supports at lowpositions becomes more and more, and the flexible accommodation bodiesare expanded to promote the stretching of the regulating supports.

When the supports at high positions and the supports at low positionsare the same in hydraulic pressure, the hydraulic medium does not flowin the high-pressure pipes any more, relative positions of theregulating supports and a bottom plate of the washing machine do notchange any more, and the automatic regulating of the washing machine iscompleted.

During the washing or spin-drying of the washing machine, the hydraulicmedium can also slowly flow for self-leveling, so that vibration noisesof the washing machine are greatly lowered.

In addition, the support for household appliance, provided by each ofthe above-mentioned embodiments of the present disclosure, can also beapplied to household appliances such as electric refrigerators, coolersand air-conditioner indoor units, besides washing machines.
